First grand duke of Hesse, loyal to Napoleon then flipped.
Compare Louis I of Hesse-Darmstadt with another historical figure:
Louis I succeeded his father Louis IX as Landgrave of Hesse-Darmstadt. He inherited a small, relatively poor state that was caught between the major powers of France and Austria.
Louis I allied with Napoleon by joining the Confederation of the Rhine. In return, he was elevated to Grand Duke and received territorial gains, including parts of the former Holy Roman Empire.
After Napoleon's defeat at Leipzig, Louis I switched sides and joined the Sixth Coalition. He was allowed to keep his title and territories, preserving his rule through the post-Napoleonic settlement.
Under pressure from liberal movements, Louis I granted a constitution to Hesse-Darmstadt. This established a bicameral parliament and limited civil rights, making Hesse-Darmstadt one of the more progressive German states.
